Would not, will not, shall not EVER use a check rein.
EVER!!
Seriously, there is NOTHING in AMHA or AMHR that says the check has to be attached to the
bit let alone to a separate bit, so, if I ever do get around to driving under AMHA rules, apart from having a rein so loose it will never actually make contact with the horse, I shall affix it to the noseband.
The real problem I have, once we get past all the rubbish about it being a safety issue (apparently only in America, the rest of the entire world manages just fine) is the fact that it alters the horses action, and not in a good way, either- why would you want to do that?
Then there is the problem of it ripping your horses mouth out if it stumbles- why would you want to risk that?
So:
If I were still active in the AMHA I would campaign to make it's use discretionary rather than the ludicrous mandatory rule - we removed that from our AMHA classes over here, I do not think it would get past the RSPCA!
OK, sorry about that, you knew it had to happen sooner or later, and I am sorry Mo for involving you in my rant, I assure you none of the comments made here are meant to be against you personally. This just happens to be something about which I am passionate.
If Shake goes well on a slack rein, why not just leave him on a slack rein?
Lead the field as opposed to following the trend??
